3x for replay, I have tried to use a external pin as the reset signal ,first tie up, then after I watch 100M, 125M clocks ok, pull the pin low, so I am sure reset time isn't the problem.

Tse don't get clocks on the phy side, only GMII interface needed signals connect between Tse and Phy, tx&rx clks all from Tse side.
